Description

Two sections stroke rivet drivers of voltage-multiplying type

The utility model relates to two sections stroke rivet drivers of a kind of voltage-multiplying type, can be easily alignment function accurately.

Rivet driver is a kind of conventional machinery that often uses, and it can very firmly be fixed together the spare part combination.Yet present employed rivet driver generally is mechanical, and it utilizes lever principle to drive a connecting rod by elements such as stamping machines and drives this rivet driver, rivet is fixed on some spare parts to be made up.There is considerable shortcoming in this traditional mechanical type rivet driver, these shortcomings comprise: 1. it utilizes mechanical stamping machine drivening rod, it is very big to produce noise during operation, not only can destroy environment, and operating personnel also can damage organs such as ear because noise is too big.2. the needed spare part of this mechanical type rivet driver is quite a lot of, and assembling is difficult and can increase cost of labor, spare part and assembly cost.3. because it adopts mechanical interlock mode,, greatly shorten the service life of machinery so have abrasion.4. have again, after this kind stamping machine touches its switch, this rivet of its impact components punching press immediately, the operator must aim at rivet hole quite modestly absorbedly, could impact the work of rivet very accurately, a this stroke maneuver makes operating personnel's spiritual wear and tear very big.

The purpose of this utility model is to provide a kind of voltage-multiplying type two sections stroke rivet drivers, and its noise is low, aims at easily.

The purpose of this utility model is to realize like this, promptly provide a kind of voltage-multiplying type two sections stroke rivet drivers, comprise a rivet seat, one send the nail groove rivet to be supplied to the top of this rivet seat, one support extends to the top of this rivet seat, one impact components be erected at this above support and also its be arranged to be moved downward to this rivet seat to carry out nail hitting action, it comprises that also a kind of Null oil-pressure cylinder actuator device links to this impact components, drive this impact components and be moved downward to this rivet seat, carry out the nail hitting operation being conducted to this rivet that send the nail groove.

The advantage of the utility model rivet driver is that it reduces noise, reduces spare part, reduces abrasion and cost, can carry out accurately being easy to alignment function, and practicality is good.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:

Fig. 1 is the schematic perspective view of the utility model rivet driver;

Fig. 2 is the part stereogram of this utility model rivet driver;

Fig. 3 is the pipeline allocation plan of this utility model rivet driver.

Two sections stroke rivet drivers of voltage-multiplying type of the present utility model, see also shown in Fig. 1,2,3, two sections stroke rivet drivers of this voltage-multiplying type comprise a rivet seat 10, one send nail groove 11, can be used to rivet is conducted to this rivet seat 10 tops, one support 15, it extends to the top of this rivet seat 10, so that be used for supporting some actuators or Null oil-

pressure cylinder

20,30,40.The mode that this rivet driver adopts Null oil-pressure to drive is carried out the nail hitting operation, can greatly reduce noise, and not need the mechanical interlinked mechanism of connecting rod, so can avoid unnecessary mechanical wearing and tearing, greatly prolongs its service life.

See also shown in Figure 3ly again, it is the configuration schematic diagram of the Null oil-pressure pipeline of two sections stroke rivet drivers of this voltage-multiplying type.Wherein, a Null oil-pressure cylinder 20 comprises a piston 21, be slidably disposed on wherein, so that this Null oil-pressure cylinder 20 is separated into a hydraulic pressure chamber 22 and an air-pressure chamber 23, one piston rod 24 links to this piston 21 and down extends this Null oil-pressure cylinder 20, this piston rod 24 can be directly as the impact components of rivet or can link a pole in addition, so that as the impact components of rivet.One Null oil-pressure cylinder, 30 one ends are established the less hydraulic cylinder of an internal diameter 31, and this Null oil-pressure cylinder and this hydraulic cylinder are inner respectively to be provided with a

piston

32,33 slidably, and these two pistons utilize a connecting rod 34 to link together, and these two

pistons

32,33 can be moved together.One spring 35 is arranged between piston 32 and the hydraulic cylinder 31, so that the hydraulic pressure chamber 22 that these hydraulic cylinder 31, one pipelines 36 are linked to this hydraulic cylinder 31 in this Null oil-pressure cylinder 20 is left in piston 32 drivings.Another Null oil-pressure cylinder 40, comprise that also one is slidably disposed on piston 41 wherein, so that this Null oil-pressure cylinder 40 is separated into a hydraulic pressure chamber 43 and an air-pressure chamber 42, one pipeline 44 links to this hydraulic cylinder 31 with the hydraulic pressure chamber 43 of this Null oil-pressure cylinder 40, so that hydraulic oil can be pumped in the hydraulic pressure chamber 22 of this hydraulic cylinder 31 and this Null oil-pressure cylinder 20.Article two,

pipeline

45,46 links to another one pipeline 47 and can be linked to a compressed air source, and this compressed air source also can be linked in the air-pressure chamber 42 of this Null oil-pressure cylinder 40, so that can drive the

piston

21,32,41 of these Null oil-pressure cylinders respectively.Some magnetic valves can be used to control the circulation of the medium of these pipelines.

During operation, compressed air can at first be conducted to the air-pressure chamber 42 of Null oil-pressure cylinder 40, so that order about piston 41 hydraulic oil of 43 li of hydraulic pressure chambers is clamp-oned this hydraulic cylinder 31, and then clamp-on the hydraulic pressure chamber 22 of this Null oil-pressure cylinder 20, so that this piston 21 and this impact components 24 are moved down a bit of distance, these impact components 24 tops are shifted near a bit to this rivet seat 10 earlier, like this, the operator can very accurately aim at spare part to be riveted at this moment, at this moment compressed air can at first be supplied to Null oil-pressure cylinder 30, so that order about

piston

32 and 33 hydraulic oil of 31 li of hydraulic cylinders is clamp-oned the hydraulic pressure chamber 22 of this Null oil-pressure cylinder 20, the segment distance that so promptly this piston 21 and this impact components 24 can be moved down again carries out real impact rivet operation.When finishing the action of a nail hitting, compressed air can be supplied to the air-pressure chamber 23 of this Null oil-pressure cylinder 20, so that, return to original position and move with the nail hitting of preparing to carry out next time with piston 21 and piston rod or upwards driving of impact components 24.

In addition, it is the same with the internal diameter of this Null oil-pressure cylinder 30 that the internal diameter of this hydraulic cylinder 31 can be designed to, and also can reach same effect.And when this hydraulic cylinder 31 was made as shown in FIG. less internal diameter, when with same strength driven plunger 32 time, the strength of the hydraulic oil that these piston 33 compressing hydraulic cylinders are 31 li was bigger, and it can obtain bigger benefit.
